To all whom, t may concern,.-

Beit known that we, XVILLIAM F. CLASS and ALBERT J. WnA'rHnRi-IEAD.citizens of the United States, residing in Cleveland, in

the county of Cuyahoga and State of Ohio, haveinvented certain new anduseful Improvements in Beer-Faucets, of which the following is aspecification, reference being had to the accompanying drawings, forminga part 1o thereof.

This invention relates to a beer-faucet having an air-forcing attachmentfor supplying air under pressure to the keg or barrel containing thebeer.

Beer-faucets having air-forcing attachments have heretofore been soconstructed that the air-forcing apparatus and the cock of the faucetare operated simultaneously.

The object of this invention is to provide a zo faucet having anair-forcing attachment permanently connected with and forming a part ofsaid faucet, both pump and faucet being operated either simultaneouslyor independ ently at the will' ot' the operator.

The object of this invention is, further, to provide a faucet having anair-forcing attachment and containing aeratiiig-chambers wherein thebeer is thoroughly aerated before its discharge through thefaucet-nozzle. The advantage ofthis construction is that the full effectof the air is imparted to agiven quantity of beer within the faucet,whereby a superior bead is produced on the beer when discharged into theglass, a greater foam being secured with less pumping, especially whenthe keg is nearly exhausted of beer.

In the accompanying drawings, Figure 1 is a central longitudinal sectionof the front portion of this improved beer-faucet. Fig. 2 isa 4o centrallongitudinal section of the rear portion of this improved faucet, saidfaucet being shown as broken into two parts in order to illustrate it ona larger scale upon the annexed drawings., Fig. 3 is a front elevation.

Similar letters of reference indicate corresponding partsl in thedifferent figures.

The faucet-tube A has a horizontal duct, a, near its front end,leadinginto the valve-eham ber b, and a lateral discharge-nozzle, c,flead ingfrom said chamber. A valve, d, having 5o a port, d. turns, preferably,on a horizontal axis within the valve-chamber I), occupying aboutone-third of its circumference, said valve being provided with stemswhich project at opposite sides ofthe fa neet. The faucettube has anenlarged secondary aerati iig-chamber,e,back ofthe duct e, and isprovided with a backwardly-projccting contracted nipple, f, which isshown as provided with an exterior flange. This chamber c is preferably6o tapered abruptly where it forms connection witl.;4 the duct a, and isshown as gradually tapered from a point near its front end toward itsrearend. The inner end of the faucettube is provided with ascrew-thread. 6

A11 extension tube, B, is attached to the faucet-tube A by meansofscrew-thretuls on its interior. rlhis extension-tube contains anenlarged primary aerating chamber, y, which preferably tapers from itsfront toward its rear 7o end. Vheu the tubes A and B are pnt togetherthe nipplef of the former extends into the larger end of the latter. Thechamber g is provided with a lateral duct h.

An air-pump, C, is mounted on the extension B. This pump is providedwith alateral duct, h', which communicates with the lateral duct h ofsaid extension-tube, being provided with a check-Valve, The pump C isprovided with an automatic induction-Valve, So which is shown as locatedon the piston 7c of said pump.

A lever, D, the lower part of which is bifureated or bail-shaped, isconnected at its forked ends Z with the laterally-projecting stems ofthe valve d at opposite sides of the faucet. The body of thislever isdiametrically opposite the port of the valve.

A piston-rod, E, is hinged at its inner end tothe piston 7c oftheair-puinp C, andishinged 9o at its outer end to the bifurcated leverD, whereby it is permitted to play laterally in respect to its axis, asit is reciprocated longitudinally by said lever. The port d of the valved is so arranged in relation to the duet a and the lever D that thelatter may have a -impregnated with the air.

point of discharge.

stroke for actuating the pump-piston of eighty degrees, or thereabout,without opening the valve of the faucet.

The operation is as follows: When it is desired to establish therequired pressure inthe keg or barrel the lever L is given a number ofrapid oscillations through the larger part of its stroke without openingthe faucet, and air is thereby forced by the action of the pump into theextension and faucet tubes and through the former into the keg orbarrel. When beer is to be drawn from the keg or barrel, the lever .L isgiven one full-stroke backward and forward. By the backward motion ofthe lever air is forced into the primary aerating-chamber g of the tubeB. This air coming directly into contact with the given quantity of beerinclosed within said chamber thoroughly aerates it, and a portion of theair passes through the contracted nipple f into the secondaryaerating-chamber c in a needlestream or jet. This jet first permeatesthe center of the tube of beer Within this secondary chamber and thenradiates laterally therein, whereby the beer is thoroughly and evenlyThe lever L is then drawn forward to the end of its stroke, and the portd of the valve d establishes communication between the duct a and thedischarge-nozzle c, and the thoroughly-aerated beer contained in thechambers g and e, sufficient in quantity to fill a glass,or thereabout,is discharged into the glass in a high state of foam, owing to itsthorough aeration near the exceedingly lively without the excessive useor' chemical ingredients for that purpose.

The invention herein described combines in a single structure all theelements of a drawing-faucet and an airforcing apparatus, in such mannerthat the latter may be operated independently of t-he former orsimultaneously therewith, at the will of the operator, the devicecombining at the same time the properties of simplicity and compactnessof construction and facility of operation.

The faucet-tube and the extension-tube car- The beer is thus mader ryinthe air-pump being detachable, they may be readily separated tofacilitate packing for transportation or forother purposes.

W'e claim as our invention- 1. rIhe combination of a faucet-spigot pro.-vided with a transverse valve-chamber, a longitudinal ductl opening intosaid chamber, and a lateral duct approximately at right angles to saidlongitudinal duct and also opening into said chamber, a valve extendingthrough said chamber beyond said faucet-spigot on opposite sidesthereof, said valve being provided with a port for connecting saidducts, occupying about one-third of its circumference, a bifurcatedlever the forked ends of which are connected to the extended stems ofsaid valve, the body of said lever being diametrically opposite the portof said valve. an air-pump the cylinder of which is fixed to saidfaucet-spigot parallel therewith, a valved duct connecting saidpump-cylinder with said spigot, and a hinged piston-rod connected at oneend to the piston of said pump and at the other end to said bifurcatedlever, substantially as described.

' 2. The combination of a faucet the tube of which is provided with anenlarged aeratingchamber, a detachable extension-tube connected withsaid faucet-tube, and also provided with an enlarged aeratingchamber,and an air-pump attached to said extension-tube and in directcommunication with the aeratingchamber thereof, substantially asdescribed.

3. The combination of a faucet the tube of which is provided with anenlarged aeratingchamber, and with a projecting nipple at the rear endof said chamber, an extension-tube detachablyconnected to saidfaucet-tube and surrounding said nipple, and an air-pump attached tosaid extension-tube and communi- 'eating therewith, substantially asdescribed.
